Application April 15, 1948, Serial No. 21,181

1 Claim. 1

By way of explanation, it might be stated that when repairing oroverhaulin the transmission or clutch of a motor vehicle, it isnecessary to remove the differential of the vehicle to provide amplespace and the necessary clearance between the forward end of the torquetube of a motor vehicle and the clutch or transmission of the vehicle,to accomplish the work.

It is therefore the primary object of the invention to provide anadapter for use in connection with the usual hydraulic jack, whereby thejack may be used in a horizontal position between the differential andan immovable or rigid element of the vehicle frame, to move thedifferential and torque tube rearwardly, providing ample space at thefront end of the torque tube for a mechanic to repair the clutch ortransmission, eliminating the necessity of removing the differential,thereby appreciably reducing the time and labor cost of repairing theclutch or transmission, to the minimum.

Another object of the invention is to provide an adapter of thischaracter having means to permit of the ready mounting of the jack onthe adapter for use in a horizontal plane, in such a way as to securethe jack in position on the adapter against accidental displacement whenthe jack is in operation to accomplish its purpose.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts, hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing:

Figure 1 is a side elevational view illustrating the application of theadapter and jack positioned for use in moving the torque tube of thevehicle construction rearwardly.

Fig. 2 is a side elevational view illustrating the adapter and ahydraulic jack as removably connected therewith.

Fig. 3 is a plan view of the adapter.

Fig. 4 is a rear elevational view of the adapter illustrating themounting tube of the adapter.

Referring to the drawing in detail, the adapter comprises the tubularbody portion 5 to one end of which is secured the plate 6, the plate 6being substantially wide and provided with outwardly and inwardlyextended flanges 1 that are spaced from the main portion of the plate 6,as clearly shown by Fig. 3 of the drawing, providing a seat for the base8 of the usual lifting jack 9, whereby the lifting jack may be readilyand easily secured to the adapter so that the lifting jack may be usedin a horizontal plane to accomplish the purpose of the jack when used inmoving the differential of a motor vehicle rearwardly disengaging theforward end thereof from associated mechanism.

At the opposite end of the body portion 5, is a relatively shortmounting tube I0 which is so arranged that it may be fitted on thelowermost bolt of the torque housing, as shown by Fig. 1 of the drawing,thereby connecting this end of the adapter with the torque housing, sothat when the jack is operated to move the differential housingrearwardly, accidental displacement of the adapter will be prevented.

From the foregoing it will be seen that when the device is positioned ina manner as illustrated by Fig. 1 of the drawing, and the boltsconnecting the ball and socket mounting assembly of the torque tube,have been removed, operation of the jack to move the lifting bar of thejack outwardly, will tend to move the rear end or differential togetherwith the torque tube, rearwardly, providing sufficient clearance at thefront end of the torque tube to permit of ready access to thetransmission or clutch, when it is desired to repair the transmission orclutch.

It is obvious that in the positioning of the adapter and jack toaccomplish the purpose of the invention, the hook forming a part of themovable section of the usual jack, is positioned over the lower plate,connecting the members of the X frame of the vehicle, the X frameconstituting the stationary or rigid section of the vehicle frame withwhich the jack and adapter are connected.

Having thus described my invention, what is claimed is:

An adapter bar for use with a lifting jack comprising an elongated body,a mounting tube secured to the side of the body with its outer end flushwith the end of the body, said mounting tube adapted to be positionedover a bolt of a torque tube housing, a plate secured across theopposite end of the body, said plate being substantially wide, the sideedges of the plate being extended forwardly and inwardly providingflanges between which the flanged base of a liftin jack, is held.
